Abstract (en)

[origin: EP2698907A1] Embodiments of the present invention provide a method and an apparatus for inverter control, and an inverter. The method includes: in a sine wave cycle, controlling a first work group and a second work group to work alternatively, to generate an alternating current which is fed back to a power grid, where the first work group includes m inverting modules, the second work group includes n inverting modules, and m is smaller than n. With the present invention, in a sine wave cycle, different quantities of inverting modules are switched and controlled to work, to make loss of an inverter adapt to a current working status and optimize the working performance of the inverter.
